Debug Custom Wordpress Plugin and Improve it

I have developed a website in wordpress and used three plug in to create a portfolio for a website. - One plug in creates new web content 'portfolio' - One plug in is used to create the portfolio page, filters and links to the web content 'portfolio' - One plug in allows for the linked portfolio to open in a pop up window. test here: [login to view URL] There is a conflict between these three plug ins which results in an unfortunate bug: CSS and javascript for the pop up fails after using the portfolio 'filters'. If we are not using the filters the portfolio page works as expected: portfolio page opens, click on one portfolio item to display a pop up presenting the portfolio content. 1) The object of this work is to debug and identify the mistake and resolve it by modifying the plug ins. (50 USD) 2) the second part is to add improvement to the plug in 'portfolio' to link it closely to the web content 'portfolio': (100 USD) improvement list: *Creating a new portfolio item (web content) automatically adds a new portfolio item on Portfolio page (ie removing the need to manually add them) *portfolios can be displayed or hidden *Portfolio categories are taken from web content * Optional: create a new plug in from the resulting code (the original code will be completely stripped after the modifications) this plug in will then be able to be used with the web content plug in for other users. (Make an offer for the development of the plug in)
